Abstract
(EN) This finned tube heat exchanger (100) is provided with: a plurality of fins (31) arranged in parallel; and a heat transfer tube (21) configured in a manner so that a medium that exchanges heat with air flows therewithin. The fins (31) are corrugated fins formed in a manner so that a hill section (34) appears in at least one position in the direction of airflow, and include: a tube periphery section (35 or 37) formed at the periphery of the heat transfer tube (21); a first inclined section (38) tilted with respect to the direction of airflow in a manner so as to form the hill section (34); a second inclined section (39) connecting the tube periphery section (35) and the first inclined section (38) to each other; and a slit (23) formed in the second inclined section (39).
(ZH)

翅片管热交换器(100)具备：平行地排列的多个翅片(31)；使与空气进行热交换的介质在内部流动的传热管(21)。翅片(31)是以在气流方向上的至少1个位置出现山部(34)的方式成形的波状翅片，具有在传热管(21)的周围形成的管周围部(35(或37))、以形成山部(34)的方式相对于气流方向倾斜的第一倾斜部(38)、将管周围部(35)与第一倾斜部(38)相互连接的第二倾斜部(39)、在第二倾斜部(39)上形成的狭缝(23)。
